An update to the code associated with the 12 / 24 hour clock inadvertently deleted the AM / PM designation for the 12 hour clock on the lower left pane of Advanced View.

Resolution:

This is a known issue that will be resolved in the next revision of Advanced View. Should you need to determine this properly, please use the 24 hour clock. This does not effect alarms or timestamps on images, only the time shown on the main page.
